I like this design... very good. Let's try a couple of variations... Put the open pill logo to the left of the PCAB (as an option). Also, try to make PCAB a little more bold.
I create a color balance to introduce conservative, truth, knowledge, trustworthy, and in the same time they are classic and elegant and easy to remember.
If there is anything you want me to change, please tell me.
Here are some more ideas. I was creating them to stand very good when are printed in black and white. Since your company works with big corporations, i am guessing that you will be sending a lot of fax, and the fax is black and white. So one of the priorities was to look very good in only black and white.
